OPEN-FACE ENVELOP.

Original application filed March 25, 1915, Serial No.

1915. Serial N0. 42,671.

To all whom it may concern:

Be it known that I, GEORGE IV. SWIFT, J12,

a citizen of theUnited States, residing at Bordentown, in the State of New Jersey. have-invented a certain new and useful Improvement in Open-Face Envelops, whereof the following is a specification, reference being bad to the accompanying drawing.

This is a division of my application Serial 16,870, filed March 25, 1915, claiming an improvement in methods of making open face envelops, such as herein claimed.

My present invention relates to envelops of the class wherein the openings in the face thereof, for display of the address, etc., are covered by transparent or translucent, material sealed thereon to prevent access to the contents of the envelops through said openings, and particularly to a construction and arrangement whereby said transparent material reinforces the envelop at its normally weak regions.

My invention includes the various novel features of construction and arrangement hereinafter more definitely specified.

In the drawing, Figure I is aplan view of an individual envelop blank creased where it is to be folded.

Fig. II is a front view of an envelop formed from the blank shown in Fig. I.

Fig. III is a rear view of said envelop shown in Fig. II.

Fig. IV is a fragmentary sectional view taken on the line IV in Figs. II and III.

In said figures; the envelop blank 1 has the opening 2 in the front portion thereof and is creased as indicated by the dash lines 4 where the blank is to be folded to form the envelop flaps 5, 6, 7. and 8. Said opening 2 is covered by the strip 10 of transpare ent or translucent material, connected with said blank by the adhesive 12. Said strip is of uniform width throughout its length but is, preferably, of less length than' the portion of the envelop blank upon which it is applied; so that, when said blank is folded to form an envelop, as indicated in Figs. II and III, said strip overlaps the rear face or flap 8 of the envelop and is covered by the end flaps 6 and 7, as indicated in Fig. IV, said flaps being thus secured by the adhesive 14 indicated in Fig. I. The flap 5 is Specification of Letters Patent.

16,870. Divided and this application filed J'ulylSO,

also provided withadhesive 15, but said flap is left open until it is desired to seal the envelop. Said strip thus reinforces the ends Patented May 29, 1917.

of the envelop, at the regions thereof in line with the opening 2, which otherwise would be weaker than the other portions of the envelop.

The construction and arrangement above described'whereby the ends of the strip are covered and concealed is preferable because the fabric of which it is formed is of a color different from that of the envelop blank 1, and consequently, if allowed to project beyond the ends: of the flaps 6 and 7 presents an unsightly appearance.

As described in the application aforesaid,-

of which this is a division, the strips are made slightly shorter than the blanks by placing the strip material under slightly greater tension than the envelop material when it is cut to form patches to cover the respective envelop openings. However, it is obvious that envelops embodying the invention herein claimed may be otherwise formed.

Therefore, I donot desire to limit myself to the precise details of construction, arrangement or procedure described, as it is obvious that various modifications may be made therein without departing from the essential features of my'invention as defined in the appended claim.

I claim An envelop having a front portion provided with an opening, a rear portion and end flaps attached to said front portion, a strip of transparent material covering said opening and extending lengthwise of the front portion and onto said end flaps said transparent strip being applied under tension which causes it to contract so as to terminate within the extreme limits of said flaps, whereby when said envelop is folded the extreme outer edge of said end flaps may be secured directly to said rear portion.

In testimony whereof, I have hereunto signed my name at Bordentown, New Jersey, this twenty-seventh day of July, 1915.
